I just made a reply to another post about SD cards. This is it: https://forum.dji.com/forum.php?mod=viewthread&tid=140866
Not sure if this will be the correct answer you are looking for. I had it in my notes that I keep on the Mavic.
In summary, there are three classes of SD cards:
SD, up to 2GB in size, formatted in FAT12 or FAT16
SDHC, from 2GB - 32GB in size, formatted in FAT32
SDXC, from 32GB - 2TB in size, formatted in exFAT
Regular SD cards, and micro SD cards are capable of any of these classes. SD card class support is backwards compatible (e.g. SDHC cards are supported in a device that supports SDXC cards), but not the other way round (e.g. SDXC cards are not supported in a device that only supports SDHC).
Because a device that supports a 64GB card must already support SDXC cards formatted in exFAT, I don't see why a larger card wouldn't be supported either. But, a card that supports up to 32GB of size only supports SDHC cards, and therefore not capable of using the larger SDXC cards.
Please remember though that there may still be devices that will not support over 64GB SD cards (even though they theoretically should), possibly due to hardware or software limitations.
